I'm pretty sure we need TSO'd headsets, so no Lightspeed.

I'm also in the market for headsets. I've been eyeing the David Clark Pro-X (would appreciate an opinion on these).

Also as far as luggage, go with the LuggageWorks. You could do Stealth series, but I've talked to others saying the Aviator series is almost just as good as long as you treat it ok.
